Abstract
A method for calibrating a vehicle to infrastructure system using an infrared camera overlooking a road, comprises: obtaining from the camera a first image, each image of the camera having points identifiable in an image coordinate system and corresponding to objects in a real world scene; identifying in the first image a plurality of points each of which corresponds to a respective object that is touching the road's surface; obtaining a measurement that corresponds to a distance from a location of the camera to each respective one of the points in a camera coordinate system (CCS); determining a model of the road in the CCS based on the points and their obtained distances; and calculating a transformation between the CCS and a world coordinate system (WCS) using the road model, the transformation being usable to determine a distance in the WCS to an object in a second image.
